Oximetric detection of intracardiac left-to-right shunts.
To assess prevailing guidelines for the oximetric detection of intracardiac left-to-right shunts, we examined the variability of right heart oxygen saturation step-ups in 1121 catheterisations in children with aortic and pulmonary stenosis, who were studied as part of the joint study of the natural history of congenital heart defects. It is estimated that in the absence of intracardiac shunting...
متن کاملRadionuclide quantitation of right-to-left intracardiac shunts in children.
A simple, noninvasive method for measurement of right-to-left intracardiac shunts would enhance the management of patients with congenital heart disease. This study describes application of data processing techniques used previously in dye-indicator curves to data recorded during the initial transit of radioactive bolus through the central circulation. Radionuclide angiocardiograms were perform...
متن کاملEchocardiographic detection of intracardiac right-to-left shunts following peripheral vein injections.
A contrast echocardiographic technique using peripheral vein injections for the detection and localization of intracardiac right-to-left shunting is described. Fifty children underwent cardiac catheterization and peripheral contrast echocardiographic studies. The site, degree, and direction of shunting were established at catheterization by oximetry, indicator dilution analysis and/or angiograp...
متن کاملLeft-to-Right Shunts
Contrary to the opinion of French pediatrician HenriLouis that isolated ventricular septal defects (VSDs) are universally well tolerated, the subsequent discoveries of Eisenmenger, Abbott, Wood, and others have taught us that the prognosis of left-to-right shunt lesions is not always benign. After more than a century of research, as pediatric cardiologists and congenital heart surgeons, we clai...
متن کاملKrypton-85 in the Detection of Intracardiac Left-to-right Shunts.
ANUMBER of methods have been developed for detecting left-to-right shunts during cardiac catheterization of which the most frequently employed is determining the difference in oxygen saturations. This method has limited application in the presence of small shunts, however, since the minimal changes are often within the error of this method.' Therefore, other more sensitive technics have been em...
